I just had the same issue last week. I was right in the middle of Open Water when it shut down and got teh H02 error. I found a really good thread that discusses this same issue on the AVS forums. Unfortunately, I don't have the URL at work. I can post later. I guess the parts are about $35 or...
I actually called my local dealer yesterday and he noted that they will not get their stock until early to mid september. I agree on paper this looks like a great deal.
